The ink has always been topmost like that. It's just the way that particular control works. I'm interested in tweaking that, but haven't done so yet. I don't believe that the ink objects respect z-order, but I'll look into that. It would be a simple answer. I believe they're a different animal, though, and I'd have to put them on a separate layer to be able to change their z-order relative to the tokens.

So, just to make sure I have this correct, the desired z-order from bottom to top is:

background

fixed objects like rocks and trees

ink

grid

active objects like character tokens

I know that some of you use the topmost-ness of the brushes to do fog of war, but I'm close to a better answer to that problem, so I think the above order would work. I'm not in a hurry to get into movable layers and having you explicitly manage layers. I'd like to keep it simple.
